US Patent:
2009012, May 14, 2009
Filed:
Nov 14, 2007
Appl. No.:
11/940281

International Classification:
G06F 5/14
US Classification:
710 57
Abstract:
A variable speed linear tape drive includes a driver portion for rotating a supply reel of a tape cartridge having storage media spooled therein, a motor coupled to rotate the driver portion, a controller configured to control the motor in accordance with a control algorithm, an interface for one or more of sending data to and receiving data from a host; and a buffer for storing one or more of data received from the host and data to be transmitted to the host, the buffer operable to supply a buffer fill level indication to the controller, wherein the control algorithm is operable to generate a difference between a target buffer fill level and the buffer fill level indication and adjust at least one of an angular velocity or an acceleration of the motor to reduce the difference.

International Classification:
G11B 15/46
US Classification:
360073070, 360073080
Abstract:
A control system and method for operating a system comprising a host computer, a buffer, a tape drive and a tape is provided. The method includes writing data to the tape while the tape is traveling at a first speed; stopping the tape; determining an optimum second speed to drive the tape to travel; and, thereafter driving the tape to travel at the second speed while writing data to the tape.
